You can stop debt collectors from calling you at work by telling them, in writing, that your employer prohibits such calls. Under the federal Fair Debt Collection Practices Act (FDCPA), 15 U.S.C. § 1692c(a)(3), a debt collector may not contact you at work "if the debt collector knows or has reason to know that the consumer's employer prohibits the consumer from receiving such communication." Once you notify them, the calls must stop.
What the FDCPA actually says. The FDCPA applies to third-party debt collectors (collection agencies, debt buyers, and law firms collecting debts they did not originate). It does not apply to original creditors collecting their own debts (though many states have parallel laws that do). The protection at work is found in 15 U.S.C. § 1692c(a)(3); the broader cease-contact right is at § 1692c(c).
Step 1: Send a written request to stop work calls. Mail a letter to the collector by regular mail and keep a copy. Email is acceptable but certified mail with return receipt creates the strongest record. The letter should be brief:
"To [Collection Agency]: My employer prohibits me from receiving personal calls at work. Pursuant to 15 U.S.C. § 1692c(a)(3) of the Fair Debt Collection Practices Act, please cease all communications to my place of employment, including the phone numbers [list any work numbers they have used] and any other work-related contact methods. You may continue to contact me at my home address [or PO Box] or by mail. Account number: [if known]. Date: [today's date]. Signature: [your name]."
Step 2: Use the broader cease-contact right if you want all calls to stop. Under 15 U.S.C. § 1692c(c), you can demand that a third-party debt collector stop all communications with you (not just at work). The collector may then only contact you to confirm receipt of your letter, to notify you that they are ceasing collection, or to notify you of a specific legal action they intend to take.
Note the trade-off: a full cease-contact letter does not eliminate the debt. If the collector decides to sue, you will not receive their communications and may not learn of the lawsuit until you are served. Some collectors escalate to lawsuit faster after a cease-contact letter. The FTC has guidance on this trade-off at consumer.ftc.gov.
Step 3: Document the calls if they continue. If the collector keeps calling at work after your written notice, write down each call: date, time, the number that called, the agent's name (ask for it), and what was said. Voice mail recordings are particularly strong evidence. Save everything.
Step 4: File complaints if violations continue. File a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov/complaint. The CFPB shares complaints with the collector, who typically responds within 15 days. CFPB complaints are public (with personal information redacted) and often produce better results than calling the collector directly. Also file with the FTC at reportfraud.ftc.gov and your state attorney general's office.
Step 5: Sue if the violations are serious. The FDCPA allows you to sue a third-party debt collector for violations and recover up to $1,000 in statutory damages, plus actual damages, plus attorneys' fees and costs (15 U.S.C. § 1692k). Many consumer attorneys take FDCPA cases on contingency because the statute provides for fee-shifting. Find one through the National Association of Consumer Advocates at consumeradvocates.org.
Special rules for the original creditor. The FDCPA does not apply when your original creditor (the bank or company you originally borrowed from) is collecting its own debt. However, many states have parallel laws (the California Rosenthal Act, the Texas Debt Collection Act, the New York General Business Law, and others) that extend FDCPA-like protections to original creditors. State attorney general websites describe specific rights.
What about the federal Telephone Consumer Protection Act? The TCPA (47 U.S.C. § 227) restricts automated and pre-recorded calls and text messages, including from debt collectors using an autodialer. If a collector sent you robocalls or robotexts to your cell phone without your prior express consent, you can revoke consent in any reasonable manner (including verbally) and continued calls violate the statute. TCPA damages start at $500 per violation, $1,500 if willful, with no cap.
Workplace privacy protections. Some employers have written policies prohibiting personal calls at work. If yours does, save a copy. The collector cannot defend continuing to call by claiming they did not know once you have notified them in writing. Some employees have told collectors verbally that the employer prohibits calls and the collector continued anyway; written notice eliminates the ambiguity.
What collectors are still allowed to do. They can call you at home (during normal hours, generally 8 a.m. to 9 p.m. local time per § 1692c(a)(1)). They can mail collection letters. They can make limited contact with third parties (your spouse, attorney, a co-debtor) to verify location information, but they cannot tell anyone you owe a debt. They can sue you in court (and continued contact about a lawsuit is permitted even after a cease-contact letter).
What collectors are never allowed to do. Threaten arrest, jail, deportation, or violence. Use obscene or abusive language. Misrepresent themselves as attorneys or government officials. Demand fees not authorized by the original contract or law. Discuss the debt with anyone other than you, your spouse, your attorney, or a co-debtor. Continue calls after a written cease-contact letter (with the narrow exceptions above). Each is a per-occurrence violation under the FDCPA.
Send the letter today. Save the copy. Document anything that comes after. The FDCPA gives you both administrative complaint paths and a private right of action with fee-shifting, and most collectors stop because they know what a violation costs them.
